a power interruption has occurred. To stop the temperature display from
flashing, touch CANCEL.
SETTING A TEMPERATURE RAMP
Temperature ramping is increasing or decreasing temperature at a given rate... a
change of temperature over a specified time. The setting is always in degrees C/Hr.
When a ramp is set, the setting will be displayed to the right of the chamber
temperature.
Note: Always set the temperature ramp before the target temperature is set. And
remember, the ramp rate can only be set to go as fast as the unit can drive the
sample if no ramp rate were used. Generally speaking, the unit will go from
temperature “A” to temperature “B” faster without a ramp rate being set.
The maximum ramp rate settable is 99.9ºC/Hr.

temperature will illuminate with the far right digit flashing.
2
Use the UP or DOWN ARROW to set the flashing digit. To move to the other
digits to be set use the LEFT or RIGHT ARROW.

When the value is set press ENTER. The ramp rate is now set.
SETTING TIMER

minutes, and 59 seconds. It can be set to be used with an auto-off function that will turn
the heater or chiller off at the end of the count down period. The auto-off function is
separate from the timer. The timer can be used without auto-off.

ARROW until the timer value sought is reached.
